| Abstract: | The platuea stresses of honeycombs and their corresponding deformationmechanisms are analysed under in-plane uniaxial loading condition. It shows that a newdeformation mechanism,plastic buckling,may occur when the bending resistability of cellis strong enough.The influences of geometry and material property of cell on the platursstresses and corresponding deformation mechanisms are discussed for elastic,perfectlyplastic materials. |

| Keywords: | honeycomb materials platuea stress plastic buckling |
